Microcontroller Based Current Flow Control Using Biometric Finger Recognition

Abstract

This project presets a current flow control mechanism using a Finger Print Sensor (FPS) and a microcontroller. The proposed system starts with enrolling the finger prints of authenticated user. Then, the users her/his figure in the FPS module to store data in its SRAM. As soon as the enrolling completed the proposed system displays a successful massage and the administrator manually closed the enroll system. After that whenever the user wants to flow current in any particular circuit, he have to press the FPS module again for authentication. If finger print matches with any of the stored finger prints then the current flow will start (in our case, we used an energy saving bulb to show the current flow). Display will give a massage “lights on”. To end the current flow user have to press the FPS module again and if the finger print matches with any of the stored finger prints then the current flow will stop. Display will give a massage “lights off.”
